Description

[0002] Diamond wire cutting fluid, also known as diamond wire cutting water-based coolant, is mainly used for diamond wire cutting of non-metallic brittle and hard materials such as monocrystalline silicon and polycrystalline silicon. It has excellent lubrication, cooling, corrosion prevention, rust prevention, and hydrogen suppression functions. The silicon wafer surface with low TTV after cutting has no wire marks and can extend the service life of diamond wire.

[0024] Example 1:

[0025] like Figure 1As shown in Figure 2, a diamond wire cutting fluid lubrication performance testing system includes a test box. The test box includes a control chamber 1, a test chamber 2, and a preheating chamber 3. The test chamber 2 is located between the control chamber 1 and the preheating chamber 3. The test chamber 2 is equipped with a test component for detecting the lubrication performance of the diamond wire cutting fluid. The preheating chamber 3 is used to protect the container holding the diamond wire cutting fluid. The preheating chamber 3 is connected to the test chamber 2. A heating component is provided between the preheating chamber 3 and the test chamber 2. The heating component is used to heat the diamond wire cutting fluid and the test component. The heating component includes a heating tube and a return pipe 17. Both the heating tube and the return pipe 17 are connected to the preheating chamber 3 and the test chamber. A fan 15 and a heating wire 16 are respectively provided at both ends of the heating tube.

[0026] The diamond wire cutting fluid lubrication performance testing system of this embodiment uses a heating component to preheat the diamond wire cutting fluid in the preheating chamber 3 and the testing component in the testing chamber 2, so that the testing temperature is maintained at the optimal detection temperature, ensuring the accuracy of the diamond wire cutting fluid lubrication performance testing.

[0027] Both the preheating chamber 3 and the testing chamber 2 are covered with a cover plate 4. One side of the cover plate 4 is connected to the preheating chamber 3 or the testing chamber 2 by a hinge, and the other side of the cover plate 4 is provided with a buckle 7. The buckle 7 cooperates with a slot, which is located on the side of the preheating chamber 3 or the testing chamber 2 opposite to the hinge. The cover plate 4 is provided to facilitate the placement and removal of a container containing diamond wire cutting fluid in the preheating chamber 3, and to coat the diamond wire cutting fluid onto the testing platform 10. During heating and testing, the preheating chamber 3 and the testing chamber 2 are closed.

[0028] The cover plate 4 has an observation window 6 in the middle; the observation window 6 allows the operator to easily observe the working status of the test components.

[0029] Temperature sensors 8 are installed in both the preheating chamber 3 and the testing chamber 2; the temperature sensors 8 can monitor the temperature in the preheating chamber 3 and the testing chamber 2 in real time to avoid the temperature from getting too high.

[0030] The testing assembly includes a test platform 10, on which a pushing unit and a test block 11 are slidably fitted. The pushing unit is driven by a cylinder to move. The pushing unit includes two push plates 12 and a pressure sensor 13 located between the two push plates 12. Due to the existence of friction, the test block 11 needs a certain pushing force to overcome in order to move relative to the test platform 10. At this time, the pressure sensor 13 will detect the magnitude of the pushing force, thereby obtaining the magnitude of the friction force. This allows the operator to calculate the change in μ before and after applying diamond wire cutting fluid to the test object using f = μ × Fn (where μ is called the coefficient of kinetic friction or sliding friction coefficient, which is only related to the material and the roughness of the contact surface, and is not related to the contact area; Fn is the normal pressure). By comparing this difference, the lubrication effect of the diamond wire cutting fluid can be determined.

[0031] The test chamber 2 is provided with an oil drain port 9 at the bottom and a collection cabinet 14 below the test chamber 2; the collection cabinet 14 and the oil drain port 9 are provided to facilitate the rapid discharge of diamond wire cutting fluid in the test chamber 2.

[0032] The control room 1 is equipped with a microcontroller and a display screen 18. The microcontroller is connected to the cylinder, pressure sensor 13, and display screen 18 via wires. The microcontroller is also electrically connected to the temperature sensor 8. A power connector and a gas connector are provided on the side wall of the control room 1. The power connector can be connected to an external power source to supply electrical energy to ensure the operation of the microcontroller, temperature sensor 8, pressure sensor 13, and display screen 18. The gas connector is connected to an external pressurized air source to ensure the normal operation of the cylinder.

[0033] The control room 1 is equipped with several control keys 19, which are electrically connected to a single-chip microcomputer.

[0034] During testing, a clean test platform 10 and test block 11 are placed in test chamber 2, and the diamond wire cutting fluid sample is placed in preheating chamber 3. Both are heated to the test temperature. First, the magnitude of the thrust required for test block 11 to move relative to test platform 10 without diamond wire cutting fluid is tested. According to f = μ × Fn (where μ is called the dynamic friction coefficient or sliding friction coefficient, which is only related to the material and the roughness of the contact surface, and is not related to the contact area; Fn is the normal force), the μ value between test platform 10 and test block 11 without diamond wire cutting fluid is obtained. Then, the cover plate 4 is opened, and diamond wire cutting fluid is applied to the upper surface of test platform 10. The test assembly is activated, and the μ value of the test object after applying diamond wire cutting fluid is obtained. The difference in the change of μ value is compared, and the lubrication effect of diamond wire cutting fluid can be determined by comparing this difference.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
